The ICALIC 2 International Multicentric Study (ICALIC2)

Clinical Evaluation of the Ease of Use of a New Indirect Calorimeter in Canopy and Face Mask Modes for Energy Expenditure Measurement: The ICALIC 2 International Multicentric Study (Second Phase)

Clinicians need to measure energy expenditure (EE) by indirect calorimetry (IC) to optimize nutritional support for a better clinical outcome, especially in patients with chronic conditions or with high risk of under- and over- feeding. However, IC is rarely used in clinical routine because the devices currently on the market are of tedious use, imprecise and expensive. An easy-to-use, accurate and inexpensive IC device (Q-NRG® CE marking n°MED 9811) has been developed to meet specifications made by and for clinicians. The ease of use of this new IC device has been first evaluated in mechanical ventilation mode. This second phase aims at evaluating the ease of use, the stability and the feasibility of the measurements with this new IC device in canopy and face mask modes for spontaneously breathing adult patients.

Study Overview

• Status: Terminated
• Conditions: Cancer; Hemodialysis; Surgery
• Intervention / Treatment: Device: Q-NRG®

Detailed Description

This study aims at evaluating the ease of use, the stability and the feasibility of EE measurements with the new IC device in spontaneously breathing adult patients with malnutrition, cancer, surgery or haemodialysis, using the canopy and face mask modes.

Patient data will be obtained from the medical records before EE measurement. EE measurement will be performed sequentially with the Q-NRG® and the IC device currently used in each study center. Patient data input, calibration, installation of face mask or canopy hood on the patient, and EE measurement recording will be performed according to the procedure stated in their respective user manual. Time needed to perform EE will be calculated afterwards from the time the IC device is turned on to EE measurement reaches a steady state with a variation ≤10%.

In a subset of 15 subjects, accuracy of gas composition (O2 and CO2) measurement by the Q-NRG® will be assessed by comparison with the reference method consisting in a mass spectrometer.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Accuracy and precision of VO2, VCO2, RQ and EE measurements.	Accuracy and precision of VO2, VCO2, RQ and EE measurements with the Q-NRG® in face mask or canopy mode will be compared to currently used indirect calorimeters.	Immediately after the measurement.
Coefficient of variation of VO2, VCO2, RQ and EE.	The stability of VO2, VCO2, RQ and EE measurements with the Q-NRG® in face mask or canopy mode will be compared to currently used indirect calorimeters.	Immediately after the measurement.
Clinical condition restriction.	Clinical conditions, if any, precluding or disturbing the EE measurement with the Q-NRG®.	Immediately after the measurement.

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
